Title: Improvements in detachable wheels for vehicles
IPC: B60B3/18
Filed: 1923-10-09
Abstract: 224,350. Owen, A. E., and Downs, R.. W. Oct. 9, 1923. Detaching from, and attaching to, permanent hubs; hubs.-Relates to detachable wheels of the kind in which the nave is secured to a permanent hub by studs passing through the nave and having securing nuts on the nave passing through holes in a rotatable securing plate or locking-ring, the holes being large enough to allow removal of the wheel without removing the nuts. According to the invention, the locking-ring is secured on the nave and is rotatable thereon through a small angle. Figs. 1 and 2 show one form in which studs d fixed to a flange A of the permanent hub pass through the nave B and a locking-ring C formed with a cylindrical barrel e, which has a flange f engaging a rabbet in the nave. To limit the rotary movement of the locking-ring or plate C, a projection j<1> on the nave enters a recess j in the flange f. This also facilitates positioning the plates C for attachment or removal of the wheel. The studs d are of enlarged diameter where they pass through the nave, being not less than the outer diameter of the nuts b. One or more spring-pressed pins F enter holes D in the plate C to retain it in the locked position, and may be pressed back by a tool to allow rotation of the plate C for detaching the wheel. In another form, the plate C,. Fig. 3, is separate from the barrel e and is held between a shoulder e<1> on the barrel and the nave B. The hub cap may be integral with the barrel e. Alternatively, the plate C may be formed in. tegral with the hub cap, which may be formed as an extension of the barrel e ; or the barrel e may be riveted to the integral plate and hub cap. A sheet-metal cover J, Fig. 3, may be provided tocover the securing nuts. A plate spring K projects through apertures k in the hub cap and secures the cover J. A screw M is turned to withdraw the ends of the spring K through the apertures k to release the cover J, which may then be removed to allow access to the securing- nuts and plate C.

Title: Improved process and apparatus for the distillation of coal tar
IPC: C10C1/04
Filed: 1950-10-20
Abstract: <PICT:0698340/III/1> A fraction rich in carbazol and a fraction rich in anthracene and phenanthrene, are obtained from coal tar by introducing the tar into the first of three fractioning columns which are connected in series and operated so that (i) all components boiling below phenanthrene are taken overhead in the first column and the bottoms are introduced into the second column, (ii) a fraction containing phenanthrene, anthracene and carbazol but free of components boiling above carbazol, is taken overhead from the second column and introduced into the third column, (iii) the required fraction rich in carbazol is withdrawn from the base of the third column, an intermediate fraction is taken off at the side and the fraction rich in carbazol is withdrawn overhead. The process is preferably carried out under reduced pressure, and the most advantageous conditions are obtained when the vacuum in the second column is the highest one.  Tar which has been freed from low-boiling components is supplied through pipe 1 into column I at a position 20 plates above the sump 4.  The pressure in column I is maintained at 500 mm. Hg absolute, and the temperature of the sump is kept at 325 DEG C.  The bottoms withdrawn from sump 4 are heated to about 350 DEG C in furnace 7, and introduced into column II which is maintained at an absolute pressure of about 35 mm. Hg. About 15 plates below the top of column II there is connected a side column 10, and below this there is another side column 9. The reflux ratio to column II is adjusted at about 8 : 1 and the head-temperature is kept at 235 DEG C.  The tar components boiling above carbazol are withdrawn from the side columns 9 and 10.  The overhead take-off from column II is introduced into column III. Anthracene and phenanthrene are withdrawn from the head of column III, carbazol accumulates in the sump 15, and an intermediate is withdrawn from side column 17.

Title: Improvements in semi-permeable membranes
Inventor: CHAPIRO ADOLPHE
IPC: G01N31/22
Filed: 1964-06-22
Abstract: Graft polymer semi-permeable membranes are made by subjecting a sheet of a perhalogenated polyolefin to ionizing radiation in the presence of an aqueous solution of a polymerizable acid containing a vinylidene group, e.g. acrylic or methacrylic acid, and an inhibitor for the polymerization of the acid, e.g. ferrous ammonium sulphate. The perhalogenated polyolefin may be polytetrafluoroethylene or polytrifluoro-monochlorotrifluorethylene.  The radiation may be obtained by X-rays, gamma-rays, neutrons and electrons. Preferably the edges of the polymer sheet are preserved in ungrafted form for support purposes by masking them, e.g. with lead, during the irradiation step.  After their formation, the membranes may be neutralized with alkali.

In operation, a nose 17a of a slide 17 is moved through a notch in the belt by a slide 11 and jaws 15 are opened by the movement of a pusher 12 on clamps 13. A rivet 4 is carried by the nose 17a towards a setting punch 5 while the rivet mandrel 4a is gripped by the jaws 15 when the clamps 13 contact shoulders 21. At the end of the stroke, levers 18 are spread apart by the nose 17a and the rivet inserted in a workpiece. On retraction of the slide 11, the levers 18 drop in behind the preformed rivet head and jaws 15 pull the mandrel to set the rivet. After the rivet mandrel has sheared, the remainder is reinserted in the extension 3a. The slide 17 has shoulder 17b which push spring-biased shafts 23 to the right as seen in Fig. 8 when the slide 11 is advanced so that claws 28 are opened and move past an extension 3a whereupon the claws are closed by a spring-loaded pusher 26. The belt 3 is held against movement until the sheared portion of the mandrel is reinserted in extension 3a by elongate shoulders 17c which extend into a notch 3b. The shoulders 17c clear the notch 3b after reinsertion of the sheared mandrel so that the belt can be driven in the direction of arrow a by springs 24.
